ABSTRACT:
Rescheduling multiple micro-operations in a processor using a replay queue. The processor comprises a replay queue to receive a plurality of instructions and an execution unit to execute the plurality of instructions. A scheduler is coupled between the replay queue and the execution unit. The scheduler speculatively schedules instructions for execution and dispatches each instruction to the execution unit. A checker is coupled to the execution unit to determine whether each instruction has executed successfully. The checker is also coupled to the replay queue to communicate to the replay queue each instruction that has not executed successfully.
